The chuck only opens and closes while installed on the dremel threaded spindle. Re-install the chuck. Screw it down as far as it will go while depressing the button stop. To open the chuck keep the button stop depressed and unscrew. The chuck will open.

It's a piece of junk! Impossible to put it on the shaft because there's a tube in there already!

Ok, so the problem is that the top teeth of the chuck is clamped shut and the previously mentioned trick of screwing it down (righty tighty) on the dremel shaft then loosening by twisting (lefty loosey) doesn't open the chuck teeth, it just removes the whole chuck back off the base. SO, with the chuck in your hand, put a very small drill bit in through the bottom of the chuck so it bumps up against the bottom of the tooth mechanism. I just tapped the drill bit with a hammer and the teeth sprang open!

If you re-install the chuck onto your Dremel threaded spindle, (righty tighty, lefty loosey), you will begin to see the chuck close. It was never addressed in the instructions, I found this out by accident. When removing the chuck from the Dremel tool, while the chuck is open, place a bit of any type into the open jaws, then loosely hold the bit in the jaws while you unscrew the chuck from the dremel.

I didn't have this problem so I can't suggest anything but using two wrenches or pliars to twist the collar.

Sandy: You have to remove the collet (the thing stuck in the tube on the dremel) when you take off the old threaded-on piece.Then the chuck should screw on the dremel tool itself (you still have to lock the tool shaft, either with a wrench or on the newer dremels with the lockout-lever above the switch).

Hi . Yes that's quite correct, like most drill presses, the chuck is held on by a Morse taper. Make sure the taper on the shaft and the bore in the chuck are both absolutely clean and undamaged then tap on the chuck with a bit of wood and a hammer. Remove the chuck with a forked wedge, I just used a pair of long nose pliers. That's all. Best regards T

Yes, I had the same problem with the safety lock. The simple fix is to take a hand drill with bit and expand the opening slightly. It still locks but opens with a mild tug. Good Luck.

Jessica, you need to "unscrew" the drill bit holder; As you do so, you will note the opening increases in size; when your drill bit will go into the drill, stop turning; then reverse the holder until it is tight around the bit. Hope this is of some help.

It was really easy to work the plastic using my dremel's rotozip/drywall bit. I think the "fold the cord in half, zip-tie, and unspool both ends" hack will work better, though.

My sis-in-law's unit came with the chuck assembly not fully bedded (not installed) thus when you twisted the chuck to open it, it wouldn't. I had to reinstall it by pressing down on it firmly but once it was fixed the chuck opens when you twist clockwise (with the bit insertion hole facing you) to letter "R" and then you insert the bit then twist counter-clockwise back to "S". The unit didn't come with any instructions but they emailed it a few days after I received it. Would've been nice had they emailed it right after it was ordered. If you haven't received the instructions, reach out to the seller or leave your email and I'll be happy to forward them to you.

Turn them straight up and down, then use a small flathead screwdriver to pry it out the first time. I had to use needle nose players to even turn them the first time. After that it opens fine.

What I did to mine was to drill and tap for a 10-32 nylon tipped set screw next to one of the recesses for the wrench. I have modified my Jet MiniVS to be reversable (easy as it is a DC motor)This way when I want to turn "in reverse" I tighten the set screw. The chuck is about 3 lbs and if spinning under load in reverse and the lathe is stopped abruptly, it could spin off the 1-8 thread of the headstock. With the nylon setscrew secured, no problem. I do slow down before shutting off just to be safe. It is a nice chuck, haven't used the MASSIVE screw chuck as I only have a 9 1/12" swing and aren't turning huge bowls.

There's no chuck key. The previous answer is the proper way to change/ remove a bit from the drill chuck.

Now that you mention it, it was in there pretty tight. I did use the correct type of screwdriver to eventually open. Im looking at the screw that was rremoved and its stripped. I guess I will tread lightly next time the screw needs to be undone. This sounds like its a defect overall in the product workmanship. Good luck.

I had the same issue. I pried the two halves apart with a small screwdriver. I was convinced that I would crack the plastic. Went very slowly and was able to open it. Good luck!!

Is this a trick question? The right way. LOL. Using the supplied allen wrench, loosen the nut by turning clockwise while pressing the blade lock. Remove the blade and replace in the reverse order.

It is ment to ungam the cutter blades. There is a place in the center of the bottom to insert it. Turn the wrench ether way and it should start again.

I used a small flat screw driver and patiently pried it open trying various sides. It did not hurt the casing. But I agree that it is a little difficult and should have an indent to allow for a tool. The screw is hardly needed.

I have gone through hundreds and this has never happened. Have you tried cleaning the unit? Maybe the piece that punctures is no longer as sharp and clogged, which will put undue pressure upon opening.

The only thing I can tell you is : hold the chuck and reverse the drill,on high speed or high torgue. Good luck ps maybe wear gloves, rubber
